Introduction

The development of communication technology has revolutionized the way we interact with each other. In recent years, cable-based communication technology has been increasingly replaced by wireless technology, where cables are replaced by radio frequencies. One example of this is the Wireless Local Area Network (WLAN). WLAN is a wireless local area network that utilizes radio frequencies (RF) and Infrared (IR) to connect users around it. Although offering convenience, one of the challenges faced by WLAN is the limited range of the signal. To overcome this problem, the use of antennas can be an effective solution to expand signals.

Understanding Yagi Antenna Design

Yagi's antenna consists of three main components: Driven Element, Reflector, and Directors. The Driven Element is an active dipole that emits a signal. Meanwhile, the Reflector functions to reflect the emission of the Driven Element, and the Directors play a role in strengthening the resulting transmitting pattern. With this structure, the antenna can produce a more focused radiation pattern, thereby increasing the reach and quality of the signal.

Simulation of Yagi Antenna Design for WLAN Applications

In this context, the design of the Yagi antenna for the WLAN application is carried out using the HFSS Ansoft Designer Simulator Software version 10.0. The designs show that the designed Yagi antenna can operate at the WLAN frequency. This antenna has a Voltage Standing Wave Ratio (VSWR) value of 1.56 at a frequency of 2.46 GHz. A low VSWR shows that the antenna can transmit and receive signals with high efficiency. In addition, this antenna radiation pattern is unidirectional and has a gain of 10.39 dB, which shows the ability of the antenna in strengthening signals in a certain direction.

Advantages of Yagi Antenna Design

The advantage of this Yagi antenna not only lies in an increase in signal range, but also in reducing interference from another direction. This makes it the ideal choice for WLAN applications, especially in a solid and electromagnetic environment. In other words, the use of antennas can increase the reliability and performance of the WLAN system as a whole.

Strategic Importance of Yagi Antenna Design

Therefore, the application of Yagi antennas in the WLAN system is not only a solution for distance problems, but also as a strategic step to improve the quality of wireless communication. The right design and the use of sophisticated simulation software allows the achievement of optimal results, thus making a significant contribution to the advancement of communication technology.

Simulation Process

The simulation process of the Yagi antenna design involves several steps:

Designing the Antenna: The first step is to design the Yagi antenna using the HFSS Ansoft Designer Simulator Software version 10.0. This involves creating a 3D model of the antenna and defining its parameters.
Simulating the Antenna: Once the antenna is designed, the next step is to simulate its performance using the HFSS Ansoft Designer Simulator Software version 10.0. This involves analyzing the antenna's radiation pattern, gain, and VSWR.
Analyzing the Results: The final step is to analyze the results of the simulation and determine whether the antenna meets the required specifications.

Conclusion

In conclusion, the simulation of Yagi antenna design for WLAN applications is a crucial step in the development of wireless communication technology. The use of sophisticated simulation software allows the achievement of optimal results, thus making a significant contribution to the advancement of communication technology. The Yagi antenna design offers several advantages, including an increase in signal range and a reduction in interference from another direction. Therefore, the application of Yagi antennas in the WLAN system is not only a solution for distance problems, but also as a strategic step to improve the quality of wireless communication.

Future Work

Future work in this area could involve:

Improving the Design: One area of future work could involve improving the design of the Yagi antenna to achieve even better performance.
